This data package was created 2025-12-17 14:19:30 by NPSTORET and includes selected project, location, and result data. The included project (SHEN_UVA_Primary) comprises data from the following sources: (1) the Shenandoah Watershed Study (SWAS); (2) quarterly sampling for the Virginia Trout Stream Sensitivity Study (VTSSS); and (3) 1987, 2000, 2010, and 2011 ('decadal') sampling for the Virginia Trout Stream Sensitivity Study. The Shenandoah Water Study (SWAS), initiated in 1979, has both scientific and resource management objectives. The underlying scientific objective of the SWAS program has been to improve understanding of hydro-biogeochemical processes and factors that govern ecosystem conditions in the mountain watersheds of Shenandoah National Park (SHEN). This scientific objective complements a resource management objective that has been defined by the need to document and assess change that is occurring in SHEN ecosystems. Only the data from SWAS and VTSSS collected within SHEN are contained in the SHEN_UVA_Primary project. Other data from these programs collected outside SHEN (e.g., on U.S. Forest Service and other lands) can be obtained from the University of Virginia or the Water Quality Portal under the USFS_UVA_Primary and OTHR_UVA_Primary projects.
